WIND'OW-SASH.

To all whom it may concern:

Be it known that I, KARL Gon'rz, a subject.

of the Emperor of Austria, residing at Detroit, in the county of lVayne' and State of hfichigan, have invented certain new and useful Improvements in Window-Sashes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to metallic window sashes, and the object .of my invention is to provide simple, durable and inekpensive and fire proof sashes embodying novel top, bottom, sides and meeting rails,'having cross sectional shapes insuring rigidity and holding means for plates of glass.

I attain the above and other objects by a mechanical construction that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein Figure l is an elevation of the inner side of window sashes in accordance with my invention;

Fig. 2 is an enlarged cross sectional view taken on the line IIII of F ig. 1;

Fig. 3 is a similar view taken on the line III-III of Fig. 1;

Fig. 4 is a similar view taken on theline IVIV of Fig. 1;

Fig. 5 is an enlarged fragmentary vertical sectional view taken on the lines V-eV of Fig. 1;

Fig. 6 is an enlarged horizontal sectional view taken on the line VIVI of Fig. 1, and

Fig. 7 is a perspective view of a portion of one of the side rails of a sash.

Considering the top sash, there are metallic side rails B, a top rail A, and a meeting rail C. The top rail A is made of a single piece of sheet metal fashioned about a filler strip 1 of less length than the toprail, which has parallel side walls 2 and 3 with the lower edges thereof forming a groove 4: to receive the upper edge of a glass plate 5 held by putty or other matter in the groove 4. Preferably one wall of the groove 4, at the inner side of the sash is of less length than the outer grooved wall, as best shown in Fig. 2, so that the outer side of the glass plate 5 will have a substantial backing or brace. The upper edge of the wall 2 is bent inwardly at an inclination and upon itself to provide a Pocket 7 for the upper edge of the Specification of Letters Patent. Application filed September 4,- 1917! Serial No. 189,454.

wall 3, said wall being bent over the filler 1 and into the pocket7, where it may be frictiona-lly or otherwise held. The pocket 7 constitutes-an overhanging ledge and permits of this portion of the window sash being easily fitted in a window frame.

. The ends of the top railA are mitered and are adapted to be brazed, soldered, spot welded or otherwise connected to the upper mitered ends of the side rails B. The side rails B are identical. in construction and are formed somewhat similar to the top rail A, that is, each side, rail is made of a single piece of metal bent about all sides ofa filler 9 with inwardly projecting short and long flanges 10 and 11 respectively forming a' groove to receive the side edges of the glass plate 5 and putty or other securing means. The side flanges are formed by bending the metal on itself and after bending the metal,

about the filler, the edges of the metal can be connected, as at 9 to form a longitudinal rib throughout the length of the rail, in a plane at a right angle tothe plane of the flanges 10 and 11, so as to cooperate there with in adding rigidity to the rail. Instead of bending the flanges 10 and 11 inwardly at an angle, the flanges are in a plane with the side edges of the rail 3, as best shown in Fig. 6. The lower ends of the side rails B are connected to the ends of the meeting rail C and the ends of the rails B and mitered, similar to the construction entering into" the rail A. The meeting rail C is formed of a single piece of metal bent to provide side walls 12 and 13 having the edges thereof connected by flanges 14. S01- dered or otherwise secured to the wall 13 of the meeting rail is a channel strip 15 that receives the lower edge of the glass plate 5, said channel strip being devoid of putty, as the putty in the grooves of the top and side rails is sufficient to hold the glass plate in position, and said channel strip is not placed in engagement with the meeting rail until the glass plate has been properly assembled relative to the upper sash.

Reference will now be had to the lower sash composed of a meeting rail D, side rails E, and a bottom rail F. The side rails E are constructed similar to the side rails B of the upper sash. The bottom rail F has two parallel walls 16 and 17 with the lower edges thereof terminating in a bottom lateral flange 18. The wall 17 has a channel member 19, similar to the channel member 15, for supporting a plate of glass 20, said plate having the. side edges thereof held in 1 the side rails E by putty or other securing smeans 21. The upper edge of the plate of 1 ment, the upper sash cannot be lowered or the lower sash raised, but provision is made for swinging the lower portion of the upper sash outwardly, by such devices generally designated 25 and forming no part of the present invention.

One embodiment of my invention has been illustrated, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall 7 4 within the scope of the appended elalm.

gs. 3 and 6, it will be What I claim is: I

A metallic window sash composed of side rails, top and bottom rails, fillers in said side and top railsy'and all of said rails having mitered ends secured together,-each side rail being formed of a single piece of metal bent to provide two-ply flanges forming grooves adapted to receive the side edges of a pane of glass and a space for the filler of said side rail with the flanges and edges of the rail wholly outside of the filler space, each piece of metal having its longitudinal edges connected to form a rib in a plane at an angle to said flanges, and a channel member carried by the bottom rail of said sash and adapted to receive the lower edge of the pane of glas mounted in the grooves ofsaid side rails.

In testimony whereof I afiix my signature in the presenceof two witnesses.
